Determination of the Bond Work Index of Ores A.J.C.Taguiam Department of Mining, Metallurgical and Materials Engineering University of the Philippines, Diliman [email protected] Abstract The Bond work index refers to the measure of a material's hardness or resistance to crushing and grinding, and is numerically expressed as kilowatt hours per short ton.

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 10 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.

Use of Work Index Since its introduction in the 1960s the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw. Along with comminution circuit design the work index parameter is widely used in tracking mill performance. Due to the age and lack of controls for the test many

Bond Ball Mill Index Test JKTech. The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
